i just checked my codes and they read 0705 which on the ECU Decoder site that it was undefined. The other code is 0806 and came up as EVAP canister purge control valve/solenoid valve. Does anyone know that this code means and does anyone know what 0705 is? this code has happened a couple times now. Any input is greatly appreciated.

Thanks. Kiwon.

 

If you had done a search on 0705 you would have come to this post by Bill.


Diagnostic Trouble Code 0705 points to a problem with the Evaporative Emission Control System.

This malfunction is detected when the EVAP control system has a leak or the EVAP control system does not
operate properly. (EVAP = EVAPorative emissions.) Possible causes include...

- incorrect fuel tank vacuum relief valve
- incorrect fuel filler cap
- fuel filler cap vent remains open or fails to close
- foreign matter caught in fuel filler cap
- a leak in the line between the intake manifold and the EVAP Canister Vacuum Control Valve
- foreign matter caught in the EVAP CVCV
- leaks in the EVAP canister or fuel tank
- leaks in the EVAP purge line (pipe and rubber tube)
- EVAP purge line rubber tube bent
- blocked or bent rubber tube to EVAP control system pressure sensor
- loose or disconnected rubber tube
- EVAP CVCV and circuit
- EVAP Canister Purge Volume Control Solenoid Valve and circuit
- absolute pressure sensor
- tank fuel temperature sensor
- MAP/BARO switch solenoid valve and circuit
- blocked or bent rubber tube to MAP/BARO switch solenoid valve
- O-ring of EVAP CVCV is missing or damaged
- water separator
- EVAP canister saturated with water
- EVAP control system pressure sensor
- refueling EVAP vapor cut valve
- ORVR system leaks

This is a "jackpot" code. It points to so many possible causes as to be almost useless. It may be accompanied
by another DTC which is more specific.

 

thanks for the info.

Kiwon.

 

I suggest clearing the ECU and see if it comes up with the same code again. It could be as simple as a loose gas cap. I had that come up and it ended up being the EVAP control valve. Cost me $120 at the nissan dealership. Good luck
